Guys, there's a few variables we need to consider this year.
Firstly, the jet stream is still awkwardly positioned in an omega pattern. So, even though warm air is pluming up towards us, we still have low pressure surrounding is which is making our weather still quite volatile.
Secondly, we haven't had any considerable heating yet. It's only really been 'warm' for the past couple of days. I reckon towards the end of the week when we've had consistent, and significant ground level and atmospheric heating, we will start to see more versatile storms. These storms may even be homegrown for once, instead of relying on systems that travel from the south over the Channel.
I never expected last night to be anything special, there just hasn't been the conditions to validate any significant storm activity.
Just my two cents.
